[android-developers] Re: Strange force close on Froyo phone, works fine on ICS tablet

I was wrong about one point here, so this post is to correct that error.
Sorry. But now, the plot thickens (maybe)....

I was WRONG about this point! It does NOT work earlier in the code on my
MB520 phone (Froyo). I wasn't thinking about the fact that the
PorterDuff merge is in the method that blends filters ... but ONLY if
MORE THAN ONE filter is used. I re-did that test, using TWO filters,
and it gave me the same force close. Now I have to wonder if I did the
test the right way before, or did I just apply one filter.....

Just to be sure, I re-did the test on my Acer A500 (ICS), as well. It,
as it has done all along, worked fine with multiple filters.

I just thought of something: could this have anything to do with
Eclipse's claim that android.graphics.PorterDuff and a.g.P.Modes are
never used?
